Superset

Superset is the specialized terminal application designed for the modern engineer utilizing AI coding assistants via the command line. It solves the bottleneck of sequential agent execution by enabling you to run ten or more CLI agents—such as Claude Code or Codex—simultaneously on your local machine. This dramatically accelerates development cycles by transforming waiting time into parallel task execution and facilitating rapid context switching.

Key Features

Superset integrates the power of parallel processing and secure workspace management to optimize your development workflow.

🚀 Run Agents in Parallel

Eliminate unnecessary waiting time by launching 10+ instances of your favorite CLI coding agents concurrently. This core capability allows you to spin up new, complex coding tasks immediately while previous agents are still running, maximizing the utilization of your local machine resources and ensuring continuous productivity.

🌳 Automated Worktree Isolation

For each parallel task, Superset utilizes git worktrees to clone a new, isolated branch on your machine. This ensures every agent operates in a pristine, organized environment, preventing dependency conflicts and simplifying environment setup. You can automate copying environment variables and installing dependencies via a custom configuration file (.superset/config.json).

🔒 Private, Offline First Architecture

Designed for security and data control, Superset ensures your sensitive source code never leaves your machine. The application is fully functional offline, as all processing and agent interactions happen locally. This architecture provides maximum privacy and compliance, guaranteeing that your proprietary data remains under your direct control.

🧠 Coordinated Terminal Management

Superset acts as an intelligent coordinator, monitoring all running agent processes across multiple terminals. It provides timely notifications when tasks are completed or changes are ready for review, helping you quickly coordinate outputs and switch focus between tasks as they require your attention.

Use Cases

Superset is engineered to support demanding development scenarios where speed and isolation are critical.

1. Accelerated Prototyping and Solution Scouting: Simultaneously assign three different agents to explore distinct implementation approaches or API integrations for a new feature. Compare the results side-by-side in isolated worktrees, drastically cutting down the time required for initial solution scouting and validation.
2. Continuous Testing and Refactoring: While one agent is dedicated to running a comprehensive, time-intensive test suite in an isolated environment, deploy a second agent to focus on refactoring a legacy module. This ensures that essential background processes do not block immediate, proactive development work.
3. Effortless Context Switching: When a complex agent task is waiting for external input, a long compilation, or dependency resolution, immediately switch to a new worktree to launch an unrelated, high-priority task (e.g., generating documentation or fixing a minor bug). Superset manages the background state of the primary task, allowing you to maintain high productivity without losing context.

Why Choose Superset?

Superset is built to enhance, not replace, your existing tools, providing a powerful layer of optimization and security that traditional terminal environments lack.

• Unmatched Workflow Compatibility: Superset acts as a "superset" of the best AI coding tools. It integrates seamlessly with the CLI agents you already rely on (Claude Code, Codex, and others), allowing you to improve your existing agent workflow without requiring migration or adopting a new ecosystem.
• True Data Sovereignty: By being Offline First and featuring zero telemetry by default, Superset guarantees that sensitive project data and proprietary code remain strictly on your local machine. No data leaves your machine unless you explicitly connect to external services.
• Auditable Open Source Codebase: The application is fully open source. Engineers can inspect, audit, and contribute to the code, ensuring there are no black boxes or hidden functionalities and building maximum trust in the tool handling your critical source code.

Conclusion

Superset transforms the way you interact with AI coding assistants, turning traditionally sequential development tasks into parallel streams of high-velocity productivity. For engineers demanding speed, seamless isolation via git worktrees, and complete control over their data, Superset provides the specialized environment necessary to leverage the full power of modern CLI agents.
